A new modified spatial approach for monitoring non-perennial river water availability using remote sensing in the Tankwa Karoo, Western Cape, South Africa
(AJOL, 2021)
Non-perennial rivers (N-PRs) make up two thirds of all rivers in South Africa, yet many are ungauged.
Traditionally, it has been assumed that when a flow is recorded, there is water throughout that river. These
assumptions ...
Leveraging Google Earth Engine platform to characterize and map small seasonal wetlands in the semi-arid environments of South Africa
(Elsevier, 2021-07)
Although significant scientific research strides have been made in mapping the spatial extents and
ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is ...
Leveraging Google Earth engine platform to characterize and map small seasonal wetlands in the semi-arid environments of South Africa
(Elsevier, 2022)
Although significant scientific research strides have been made in mapping the spatial extents and
ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is ...
Modeling the geographic spread and proliferation of invasive alien plants (IAPs) into new ecosystems using multi-source data and multiple predictive models in the Heuningnes catchment, South Africa
(Taylor and Francis, 2021)
The geographic spread and proliferation of Invasive Alien Plants (IAPs) into new ecosystems
requires accurate, constant, and frequent monitoring particularly under the changing climate to
ensure the integrity and resilience ...
Use of multispectral satellite datasets to improve ecological understanding of the distribution of Invasive Alien Plants in a water-limited catchment, South Africa
(Wiley, 2020)
Invasive Alien Plants (IAPs) pose major threats to biodiversity, ecosystem functioning and services. The availability of moderate resolution satellite data (e.g. Sentinel-2 Multispectral Instrument and Landsat-8 Operational ...
Effect of landscape pattern and spatial configuration of vegetation patches on urban warming and cooling in Harare metropolitan city, Zimbabwe
(Bellweather Publishing, 2021)
The spatial configuration of vegetation patches in the landscape has implications for the provision of ecosystem services, human adaptation to climate change, enhancement, or mitigation of urban heat island. Until recently, ...
Fine-scale multi-temporal and spatial analysis of agricultural drought in agro-ecological regions of Zimbabwe
(Taylor & Francis, 2022)
This study utilised multi-temporal satellite data to characterize droughts across the five Agro-ecological zones (AEZ) of Zimbabwe at monthly, seasonal, sub-seasonal and annual scales (2000 to 2018) using a combination of ...
Use of remotely sensed derived metrics to assess wetland vegetation responses to climate variability-induced drought at the Soetendalsvlei wetland system in the Heuningnes Catchment, Western Cape province, South Africa
(Taylor and Francis Group, 2021-11-11)
Wetland vegetation plays an important role in the environmental functioning of wetlands through the provision of ecosystem services, such as food and critical habitat for organisms that live in or near water resources. The ...
Pansharpened landsat 8 thermal-infrared data for improved land surface temperature characterization in a heterogeneous urban landscape
(Elsevier, 2022)
Challenges associated with adolescents are prevalent in South African societies. During the adolescence stage, children may become involved in deviant behaviour. Although a significant number of studies have focused on the ...
Evaluating the impact of land use and land cover change on unprotected wetland ecosystems in the arid-tropical areas of South Africa using the Landsat dataset and support vector machine
(Taylor and Francis Group, 2022)
The study explored the impact of Land Use and Land Cover (LULC) change dynamics in relation to the condition and status of an unprotected wetland located in the arid-tropical parts of the Limpopo Province, South Africa. ...
